Embodiment Construction

[0049] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0050] In a typical configuration of the present application, the terminal, the device serving the network and the trusted party all include one or more processors (CPUs), input / output interfaces, network interfaces and memory.

[0051] Memory may include non-permanent storage in computer readable media, in the form of random access memory (RAM) and / or nonvolatile memory such as read only memory (ROM) or flash RAM. Memory is an example of computer readable media.

[0052] Computer-readable media, including both permanent and non-permanent, removable and non-removable media, can be implemented by any method or technology for storage of information. Information may be computer readable instructions, data structures, modules of a program, or other data. Examples of computer storage media include, but are not limited to, phase change memory (PRAM), static rando...

Abstract

The invention aims to provide a charging method and device based on temperature monitoring. By monitoring the temperature of a battery of the device, setting a limit threshold temperature (slightly lower than the over-temperature protection temperature of the battery) and restoring the threshold temperature, the battery maintains the higher charging current for a long time at the constant-currentcharging stage and under the condition of ensuring that the temperature of the battery of the device does not exceed the standard, the overall charging current at the constant-current stage is improved, and the charging time is shortened. According to the invention, the charging speed and the temperature rise can be considered simultaneously in the quick charging process. The method and the devicecan be applied to the field of consumer electronics, in particular to the small-sized or miniature electronic devices.

Description

technical field [0001] The invention relates to a charging method and equipment based on temperature monitoring. Background technique [0002] At present, fast charging has become a standard configuration in the field of consumer electronics, and it has also become popular in wearable devices. But the smaller the size of the electronic device, the more difficult it is to solve the temperature rise problem caused by fast charging. However, due to size and material limitations, the heat dissipation measures that can be added are more limited in improving the temperature rise problem, and the market has higher and higher requirements for computing power and fast charging performance of this type of product. The problem of charging temperature rise is becoming more and more prominent. [0003] At the same time, wireless charging has become popular, but the thermal power consumption of wireless charging is higher than that of wired charging, and the problem of charging temperat...
